In
1841, John
Couch Adams began investigating the by then quite large
residuals in the motion of Uranus. In 1845, Urbain Le Verrier
started to investigate them, too. Adams presented two different
solutions to the problem, assuming that the deviations were
caused by the gravitation from an unknown planet.

Sept
30, 1846 --- one week after the discovery of Neptune, Le
Verrier declared that there may be still another unknown
planet out there. On October 10, Neptune's large moon Triton
was discovered, which yielded an easy way to accurately determine
the mass of Neptune, which turned out to be 2% larger than
expected from the perturbations upon Uranus.

Another
attempt to find a trans-Neptunian planet was done in 1877
by David Todd. He used a "graphical method", from the residuals
of Uranus, he derived elements for a trans-Neptunian planet:
mean distance 52 a.u., period 375 years, magnitude fainter
than 13.

In
1879, Camille Flammarion added another hint as to the existence
of a planet beyond Neptune: the aphelia of periodic comets
tend to cluster around the orbits of major planets. Jupiter
has the greatest share of such comets, and Saturn, Uranus
and Neptune also have a few each.

Percival
Lowell, most well known as a proponent for canals on Mars,
built a private observatory in Flagstaff, Arizona. Lowell
called his hypothetical planet Planet X, and performed several
searches for it, without success. Lowell's first search for
Planet X came to an end in 1909, but in 1913 he started a
second search, with a new prediction of Planet X: epoch 1850-01-01,
mean long 11.67 deg, perih. long 186, eccentricity 0.228,
mean dist 47.5 a.u. long arc node 110.99 deg, inclination
7.30 deg, mass 1/21000 solar masses. Lowell and others searched
in vain for this Planet X in 1913-1915. In 1915, Lowell published
his theoretical results of Planet X. It is ironic that this
very same year, 1915, two faint images of Pluto was recorded
at Lowell observatory, although they were never recognized
as such until after the discovery of Pluto (1930).

Japanese scientists eye Planet X Candidate TOKYO (AFP) - Scientists at a Japanese university said Thursday they believed another planet up to two-thirds the size of the Earth was orbiting in the far reaches of the solar system...

Something
out there beyond the farthest reaches of the known solar system
seems to be tugging at Uranus and Neptune. Some gravitational
force keeps perturbing the two giant planets, causing irregularities
in their orbits. The force suggests a presence far away and unseen,
a large object that may be the long- sought Planet X. The last
time a serious search of the skies was made it led to the discovery
in 1930 of Pluto, the ninth planet. But the story begins more
than a century before that, after the discovery of Uranus in 1781
by the English astronomer and musician William
Herschel. Until then, the planetary system seemed to end with
Saturn.Today, scientists accept theories concerning plate tectonics.
There are articles and studies showing that, at one time, all
of Earth continents were on one side of the planet. What the stories
don't explore is the question, if all the continents were on one
side, what was on the other? The other side has been described
as a tremendous gap, matching the Sumerian story of how the Earth
came about. The Sumerians said Earth was really half a planet
called Tiamat, which broke up in a collision with Nibiru, [or
Planet X].

The
discovery of new planets has, in the last two hundred years,
owed more to the science of mathematics than it has to the design
of bigger and better telescopes. The unaccounted-for mathematical
irregularities in the orbits of the outer planets have prompted
astronomers to speculate upon the existence of a further, undiscovered
planet. Astronomers are so certain of this planet's existence
that they have already named it 'Planet
X' - the Tenth Planet.

To this
day, the search continues for a PLANET X. One day soon we just
might find a planet that matches the Sumerian descriptions for
a planet 4-8 times the size of earth, on a highly 3,600 elliptical
orbit around our sun. Continue to "page 3" to learn
